Attack trees provide a method of systematically analyzing security of a system. Consider a scenario where one of the companys sensitive file (e.g., companys latest financial report) is stored on the laptop of the companys CEO who frequently goes on a business trip. Draw an attack tree showing possible ways that the content can be leaked. Each node in the tree will be labelled with an attack goal. The root node corresponds to the ultimate attack goal (e.g., accessing some information in the file). The child nodes of a node represent possible ways that the attacker make progress towards the final goal.
